摘要：
The invention relates to cellular polyisocyanate polyaddition products having a density according to DIN EN ISO 845 between 200 and 800 kg/m
3 , and prepolymers composed of at least one diisocyanate (a) and at least one polyether alcohol (b), wherein the at least one polyether alcohol (b) contains the following components: (b1) aliphatic polyether alcohols having a number-average molecular weight of 300 to 1000 g/mol, (b2) aliphatic polyether alcohols having a number-average molecular weight of 2000 to 10000 g/mol, and (b3) aliphatic polyether alcohols having a number-average molecular weight of 10000 to 100000 g/mol, to a method for the production thereof, to a cellular polyisocyanate polyaddition product produced in such a way, and to the use thereof as damping elements in vehicle manufacturing.
